hand im not proud of #2

How the hell do you handle these tiny bets? I run into this all the time at NL100 and they confuse the hell out of me. I desperately need a line..

Villain is 50/20. The only hand I have on him that went to showdown is where he cbet into overs with mid pair, and checked the next two streets for a free showdown.
